Subject: lightdm-gtk-greeter: white screen until I click a mouse button, with 2 screens

Date: Mon, 11 May 2015 23:23:47 +0200

Package: lightdm-gtk-greeter
Version: 2.0.0-2
Severity: important
Tags: upstream
Forwarded: https://bugs.launchpad.net/ubuntu/+source/lightdm-gtk-greeter/+bug/1426664

After upgrading lightdm-gtk-greeter on my laptop, the screen was
entirely white. I was wondering why, while there was no such problem
on another machine, and after Googling, I've found:

  https://bugs.launchpad.net/ubuntu-mate/+bug/1426664

where it appears that this problem occurs when there are two screens,
which is the case with my laptop.

I also thought that lightdm-gtk-greeter wasn't working at all, until
again I read this bug report, where it is said one just needs to
click. So, there's a workaround, but the user may be blocked without
noticing it.

or perhaps https://bugs.launchpad.net/lightdm-gtk-greeter/+bug/1410406

I also see a 100% CPU usage (but the screen is white, not black).

Control: retitle -1 lightdm-gtk-greeter: white screen and 100% CPU usage until I click a mouse button, with 2 monitors

should be a bit better.

Does setting active-monitor=0 fix your problem?

Thanks for the confirmation, so at least you have a workaround for now
(as a side note, I didn't experience that for now on multi-monitor
setups I have).
